When automatic ZFS snapshots are enabled and an timezone DST change occurs. Shapshots taken before time change are not deleted when expired.
My experience :
- Automatic snapshots : dayly at 20h00, keep them for 30 days.
- Time zone is Europe/Paris
- Timezone change was 27th, 10/2013
- Snapshots from september are still present (now november the 18th)

    I see this also, but not depending on a dst Change. My snapshots stay even after the lifetime, when i switched off the nas server for some days. The older snapshots never got deleted then. If the server is up running 24h/day the delete of the snapshots older the given lifetime is working perfectly.
